Socket Head Cap Screw Fine & Full Thread Black Steel 1-1/4-12 * 3" Grade 8 [Cup Point] [Allen Drive] length_2-3-4 The screw has a lengthWith a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head. Black oxide steel screws are mildly corrosion resistant in dry environments. Fine and extra fine threads are closely spaced to prevent loosening from vibration: the finer the thread, the better the resistance. They are not compatible with coarse threads.
